Patented Jan. 17, 1933 UNITED STATES PATENT OFFICE WILLIAM T. DEMPsEY, 0E PHILADELPHIA, :PENNSYLVANIA BOOKMARK Application led March 311932.4 Serial No..:602,18

sion of a bookmark which may be inserted 1n a book in a manner giving the appearance s and effect of a bookmark bound into the book, which is readily detachable for insertion in another book, but when inserted, is securely held against accidental displacement.

A further object of my invention is the provision of means facilitating the merchandising of my improved bo-okmark, and presenting to the eye of a prospective purchaser R the mode of operation and use thereof without the necessity of verbose description. Such merchandising means further provides means to protect the ribbon forming a part of the marker against tearing, fraying, mussing or soiling.

In its preferred form, my invention consists of a detachable bookmark comprising a flexible finder, such as a ribbon, for insertion between the book leaves, and a setaceous retaining member housed by the b'ookbinding and forming an anchorage for an end of the finder fixed to the body of the retaining member. The retaining member may be conveniently formed from a folded strip lapped over i' resilient iilaments, such as horse-hair, which project far enough from the sides of the folded strip to be bent by insertion into housed position in the binding and yieldingly resist removal therefrom. The ribbon may also have an end housed between the laminations ofthe nder which are secured together by a suitable adhesive. The ilaments are of suiicient resiliency to cause them to give and permit the extraction of the retaining member from the bookbinding when a su'cient pull is given the ribbon.

1vVhen not in use in a book, my improved bookmark is preferably combined with a pro tective carrying case composed of thin sheet material bilaterally or trilaterallyfolded into an open end envelope. A representation of a book may be 'printed on the front of the envelope and a slit cut therein adjacent to the top of the back of the illustration of the book. The retaining member is inserted 4drawing in illustration of'a preferred em- Vthrough this slit and vthe ribbon is wound y around a leafy or leaves of the envelope which may -be retained in folded position by Ia `tongue cut from one leaf thereof and engaged in a complementary slot cutin another .leaf. k5

The .characteristics and advantages of'my invention will more vfully appear from Vthe Afollowing.description and the accompanying bodiment thereof. y Go In `the drawing, Fig. l is a broken eleva# .tion of a detachable bookmark embodying'my invention; Fig. 2 is` a partly 'broken front elevation of a containerwith my improved bookmark 'housed therein in accordance with myinvention;Fi g. 3 is afragmentary .view of a modified formof container partly Kopen; Fig. lfis a fragmentary perspective view of a book ywith my bookmark inserted therein for u se and Fig. 5 is a fragmentary vertical vsectlQIlalview throughtheback ofgthebookbindfing showing Athe lower portion of the booki mark retainer with the ilam'ents'inengagement with the binding. y

4As .illustratedin the drawing,'a strip of I' sheet material 1 Ais foldedr so as -to embrace between the laminations 'thereof kthe Vsheaf or layer of resilient 'filaments 2, such as natural or artificial 'horse4hair, fine springwire, or the like. The laminations are secured to'the filaments 2 and to one anotherby an adhesive 3, which also secures'between the laminations a ribbon 4c. n

As illustratedin Fig.l 2, a container for the'bookmark is provided-by a folder 5 bent along they crease 6 and having printed there' on an illustration `7 of abovok .with its back 'Sfand side 9`toward the spectator. lA slit 10 is cut `in the front leaf of thefolder 5 atzthe top of thebook'back 8 andl notches ll, `v11 are formedin the bottom and .front edge of the front-leaf of the folder "5.. Altongue `12 is hinged tothe front leaf of the folder 5 and passes through a slit 13 in the back leaf 5 of the folder.

For merchandising and demonstration, the retaining member l is inserted in the slit 10 of the container so that the filaments 2 are housed between the front and back leaf of the folder 5, and the ribbon 4L is bent over the l front leaf of the folder 5, passes downwardly between the leaves of the folder, is engaged in the notch 11, bent upwardly over the front face of the folder and has its end secured in the notch 11 with its free end housed betweenl the folder leaves. By inserting the tongue 12 in the slit 13, the leaves of the folder are secured together.

As illustrated in Fig. 3, the front leaf 5 of the container may have a leaf hinged along veach edge thereof. In this modification of the container the notch 11 may be omitted 'and the inturned leaf 5a notched to form a tongue 11a for receiving the folded end of the ribbon. A tongue 12a is also cut in the inturned leaf 5a for insertion in a slit '13a formed in the leaf 5b, which overlaps the leaf 5a when the container is closed.

Inthe practical utilization of my improved bookmark, the retainer formed by the body `1 and filaments 2 is pushed down between i vthe back strip 14 of the binding and the back edges of the leaves 15 of a book 16. The

length ofthe filamentsv 2 is greater than the thickness of the book andI consequently the filaments are bent, as shown in Fig. 5, and bear outwardly against the sides of the back strip lfl'with their ends frictionally contacting therewith. The frictional engagement firmly anchors the retaining member -against accidental displacement, but when the riblrbon 4 of the member 1 is firmly grasped and pulled, the fila-ments are bent and yield suflficiently Ato permit the removal ofthe retainer from the housing formed by the bookbinding. The ribbon is used in the usual l way as afguide for locating a desired place n `in a book.

Having described my invention I claim- 1. A detachable bookmark comprising a finder and a setaceous retainer. n Y.

.2. A detachable bookmark comprising a 'finder and a retainer comprising resilient anchoring Y devices.

3. A detachable bookmark comprising a4 `finder and a retainer having elastic filaments yproj ecting laterally therefrom.

4.. A detachable bookmark comprising a finder and a retainer bent over a layer of setaceous members. Y

5. A detachable bookmark comprising laminated sheet material, setaceous members engaged betweeny said laminations, andY aA ribbon engaged between said laminations.

In testimony whereof I have hereunto set my hand this 27th day of February, 1932.

WILLIAM T. DEMPSEY.'
